What Is an EGR Delete Kit?

If you’ve been around diesel trucks for a while, you’ve likely heard about EGR delete kits. Some truck enthusiasts swear by them, while others are left wondering what the fuss is all about. If you’re curious about what an EGR delete kit does, why people use it, and whether it’s the right choice for your truck, here’s everything you need to know.

What Is the EGR System?

EGR stands for Exhaust Gas Recirculation. It’s an emissions control system that redirects a portion of your exhaust gases back into the engine. This helps reduce harmful nitrogen oxide (NOx) emissions.

While it’s beneficial for the environment, the EGR system often causes problems for diesel engines. It introduces dirty exhaust gases into the engine, which can lead to carbon buildup, clogged intake valves, and reduced performance. For truck owners who prioritize power and reliability, the EGR system can feel more like a liability than a benefit.


What Does an EGR Delete Kit Do?

An EGR delete kit removes the EGR system entirely. This means:

  • No more recirculated exhaust gases.
  • No more carbon buildup.
  • Unrestricted airflow for your engine.

Here’s what you typically get with an EGR delete kit:

  • Block-Off Plates: To seal the ports where the EGR system was connected.
  • Coolant Reroute Hose: To bypass the EGR cooler.
  • Hardware and Instructions: Everything needed for installation.

Once installed, your engine runs cleaner, cooler, and more efficiently.


Why Use an EGR Delete Kit?

For diesel enthusiasts, the benefits of an EGR delete kit are clear:

  1. Improved Performance
    Removing the EGR system allows your engine to breathe freely, resulting in better throttle response, increased power, and smoother operation.

  2. Reduced Maintenance Costs
    The EGR system is prone to clogs and failures. By deleting it, you eliminate a major source of potential repairs.

  3. Lower Engine Temperatures
    Without hot exhaust gases re-entering the engine, it runs cooler. This reduces wear and tear on components.

  4. Fuel Economy Boost
    With less strain on the engine and improved airflow, you may see a small improvement in fuel efficiency.


Using an EGR delete kit on public roads can result in fines and issues with emissions inspections.

How to Install an EGR Delete Kit

If you decide an EGR delete kit is right for your truck, here’s a general installation process:

  1. Prepare the Truck
    Park on a flat surface, let the engine cool, and disconnect the battery.

  2. Drain Coolant
    Remove enough coolant to work on the EGR system without spillage.

  3. Remove EGR Components
    Unbolt the EGR valve, cooler, and pipes. Keep track of all hardware.

  4. Install the Delete Kit
    Follow the instructions to attach block-off plates and reroute coolant lines.

  5. Test and Verify
    Refill coolant, reconnect the battery, and start the engine to check for leaks or issues.
